ABSTRACT:
An inverter arrangement for converting DC to AC having a first inverter with an input for receiving DC and an output for providing a first inverter output, a second inverter having an input for receiving DC and an output for providing a second inverter output, an AC output circuit having a first input for receiving the first inverter output, a second input for receiving the second inverter output, and an AC output for providing AC based upon the first inverter output and the second inverter output, and a controller for controlling the first inverter to minimize DC content in a first inverter output, and for controlling the second inverter output based upon DC content between the first inverter output and the second inverter output to minimize DC content in the second inverter output.
